GANG -PLOW.

SPECIFICATION forming part of Letters Patent No. 603,979, dated May10,1898. Application filed March 1'7, 189 7. Serial No. 628,040. (Nomodel.) Patented in Canada January 28, 1896, No. 51,157.

To aZZ whom, it may concern.-

Be it known that I, WILLIAMSTEPHENSON, a subject of the Queen of GreatBritain, residing at Morris, in the county of Provincher, Province ofManitoba, Dominion of Canada, have invented certain new and usefulImprovements in Gang-Flows, of which the following is a specification.

My invention relates to an improved construction for the mounting of theseveral plows, together forminga gang-plow,whereby each plow is sosupported as to be capable of independent adjustment as well asindepend-' ent movement, when the latter may be necessitated by anobstacle, and whereby the plows are at the same time properly supported.

The invention, for which I have obtained Letters Patent in the Dominionof Canada 011 the 28th day of January, 1896, No. 51,157, consists in theconstruction, arrangement, and combination of parts hereinafter fullydescribed and claimed.

Referring to the accompanying sheet of drawings, which form a part ofthis specification, Figure 1 is a plan view of a gang-plow constructedin accordance with this invention. Fig. 2 is a side elevation thereof.Fig. 3 is a rear View of a portion of the rear brace The plows aremounted in a suitable rectangular frame consisting of the front sill 1,side sills 2, and rear sill 3. A forward diagonal brace, one part ofwhich is marked 4, a

and a rear diagonal brace 5 are securely mounted between the side sills2. The forward brace consists of an upper and a lower stringer 4 and 4,respectively, connected together by the vertical slats 4", formed ofpieces of angle-iron, the slats forming a se-' ries of vertical slots 4equal in number to the number of plows mounted in the frame.

A perforation is formed in the front sill 1 in line with each slot 4 inthe front brace. Traction-rods 6 pass through these perforations. Theforward ends of the traction-rods are capped by nuts 6. On the end ofeach rod 6 between the forward face of the front sill and the nut is aspiral spring 7. The rear ends of the traction-rods terminate in hooks 6Each plow has a separate beam 8. The forward end of each beam isbroadened out vertically and is perforated to engage with a hook of oneof the traction-rods. Each beam projects through and is free to movevertically in one of the slots 4 in the forward braceand its end iscaught upon the'hooks of the corresponding rod, as is shown at 8 in Fig.2.

A suitable plowshare 9 is secured to the rear end of each beam 8 and isguided by a rod 10, projecting rearwardly therefrom and through a holein a bracket 11. A bolt 12 passes through a slot in the bracket andmakes it fast on the rear brace 5, and wooden dowels 13 keep the bracketfrom turning. The slot permits the bracket to be adjusted ver tically inrespect to the brace, so as to properly guide the plow. Should theplowshare strike a stone or other obstacle and be thrown sidewise, thedowel-pins, which are easily renewed, will give way first, permittingthe plow to swing to one side, and the other parts will be saved frominjury. l The depth ofthe furrow cut .by each plowshare is determined byan adjustable regulator-wheel 14, which is secured on the beam of eachplowshare near its forward end. The

rear end of the frame is supported by a roller 15, mounted in the rearextensions 2' 2 of the side sills 2. The roller also serves to roll theground after it has been turned by the plowshares. The frame is attachedto the engine through rods 16, connected to the ends of the front sill.

With the above-described construction the depth of the furrow turned byeach plowshare is determined by its regulator-wheel, since the forwardend of each beam, although held against lateral movement, is free tomove vertically in the corresponding slot 4to allow its regulatortofollow the irregularities of the ground and determine the depth of thefurrow without affecting the position of the other plows.

A plow such as is herein described is well adapted to be drawn byatraction-engine, and I have in another application of even dateherewith, which has been serially numbered 628,039, shown astraw-burning traction-engine, provided with a fuel-gatherer, which Ihave found especially well adapted for this purpose.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination, in a gang-plow, of a frame having a series of slotstherein, with a series of plows, the forward end of the beam of eachplow resting within and being free for vertical movement in one of theslots, substantially as described.

2. The combination, in a gang-plow, of a frame with a series of plowsheld therein by guides in the front and in the rear of the plowshares,the forward guide of each plow permitting vertical movement when in useindependently of all of the other plows, substantially as described.

' 3. The combination, in a gang-plow, of a frame with a series of plowsmounted and held therein by guides in the front and in the rear of theplowshares, the forward guide of each plow permitting independentvertical movement and the rear guides being secured by breakable pinswhich will let the plow swing to one side on striking an obstacle,substantially as described.

4. The combination, in a gang-plow of a frame, having a series ofvertical slots, of a series of plows, each provided with a beam, theforward end of which plays up and down within the corresponding slot inthe frame, substantially as described. 5. In a gang-plow, thecombination, with a frame, havinga series of vertical slots therein, ofa series of plows, each provided with a beam the forward end of whichplays up and down within the corresponding slot in the frame, and with abreakable part in the connections between the rear of each plow with theframe, substantially as described.

each provided with a beam the forward end of which plays up and downwithin the corresponding slot in the frame, traction-rods connected withthe front of the frame and with the front of the beams, and a breakablepart in the connection between the rear of each plow with the frame,substantially as described.

7. In a gang-plow, the combination, with a frame, having two diagonalbraces, one of the said braces having a series of vertical slotstherein, of a series of plows, each plow having a beam projectingforwardly through and vertically movable in one of the slots, atraction-rod connected with the forward end of each beam, a series ofadjustablebrackets mounted on the other brace, a rod on each plowprojecting rearwardly through one of the brackets, and a roller carryingthe rear of the frame, substantially as described.

8. In a gang-plow, the combination, with a frame, having two diagonalbraces and a front brace, one of the said diagonal braces having aseries of vertical slots therein, of a series of plows, each plow havinga beam projecting forwardly through and vertically movable in one of theslots, a traction-rod connected with the forward end of each beam, andspring interposed between the said rods and the front brace,substantially as described.
